I'm seeing a vast increase in attemted SIP registers too. Asterisk (f13 more or less stock via yum) seems to handle the onslaught well enough, other than filling up the logs with pages and pages of failed requests. Anyone that isn't using computer generated, large passwords for their SIP registrations is probably exeriencing the joys of someone running up their phone bills with their VOIP/POTS gateway service. I'll probably start blocking all incomming SIP (both UDP and TCP) except from known peers and clients. Luckily I don't have any dynamic SIP clients that roam the net at large. -wolfgang -- Wolfgang S.
